Is it really real?
Short answer: Sometimes. Producers have been busted dubbing in words and editing scenes to create confilict.
Viewers seem hip to such fabrication; in a recent poll in the US, only 30 percent of respondents believed the shows reflect what really happened.
この "hip to" はスラング的な表現ですが、いずれにせよ意味が分からないので調べます。
OneLookの検索で出てきた辞書は次ぎの二つの辞書だけでした。
・WordNetR 3.0: informed about the latest trends

単に "hip" の項を丁寧に見ると、形容詞としての "hip" の次ぎの意味と同じで、精通している/知っている対象を "to" の後に置くと "hip to something/someone" の形になる事が分かりました。
